ABSTRACT:
A marine engine is constructed having an improved component layout so as to reduce the risk of water contact with an oxygen sensor of the engine. This advantage is accomplished by providing a collection chamber that promotes drainage of any water that may enter into the chamber through an exhaust system. In one form, the oxygen sensor chamber has a lower wall and a passage thereof, both slanted downward toward the corresponding cylinder of the engine. The oxygen sensor may be shielded by a portion of the engine (e.g., by the induction system or the cylinder block) or by a portion of the corresponding exhaust system. In another variation, the oxygen sensor can be located for easily access in order to facilitate service and replacement.
